摘要

[目的] 研究贺兰山西麓腰坝绿洲土壤水分入渗特性，为当地合理利用水资源和农田灌溉提供理论依据。[方法] 在当地选取21个试验点进行野外双环入渗试验，利用不同入渗公式对实测结果进行拟合，并通过多元分析及地统计学方法分析土壤水分入渗特性。[结果] Horton公式的拟合结果相关系数高达0.963，相对误差与均方根误差分别仅为4.09%与0.046 mm/min，拟合精度要优于Philip公式与Kostiakov公式，且模型参数具有较好的物理意义。土壤质地对入渗过程有显著性影响，土壤中含砂量越高，入渗速率越大，达到稳定所需时间越短，而土壤容重与初始含水率则分别对累积入渗量及初始入渗率有一定影响。稳定入渗率最大值约为最小值的12倍，变异系数高达0.677，且由东北向西南呈现递减的趋势。[结论] Horton公式适用于描述腰坝绿洲土壤水分入渗过程，土壤性质差异对入渗过程有较大影响，同时在空间上入渗率也存在较强变异性。

Abstract

[Objective] The aim of this study was to analyze the characteristics of soil water infiltration in Yaoba Oasis on the west side of Helan Mountains

and to provide theoretical basis for utilizing water resource efficiently and determining a reasonable way for field irrigation.[Methods] The double-ring infiltration experiments from 21 test spots were carried out. The three different infiltration formulas were used to fit the experimental data. And the soil water infiltration characteristics were analyzed using multivariate analysis and geostatistics methods.[Results] The correlation coefficient of fitting results of Horton formula was as high as 0.963

and the relative error and root mean square error were only 4.09% and 0.046 mm/min

respectively

indicating that the fitting accuracy of Horton formula was better than those of Philip formula and Kostiakov formula. Soil texture had a significant impact on infiltration process

great proportion of sand components in the soil had a faster infiltration rate and had relatively shorter time required to achieve stable infiltration. While the soil bulk density and initial water content had a certain influence on cumulative infiltration volume and initial infiltration rate

respectively. The maximum of stable infiltration rate was about 12 times than the minimum one and the coefficient of variation was up to 0.677. The spatial distribution plot showed a decreasing trend of infiltration rate from the northeast to the southwest of the oasis.[Conclusion] Horton formula could be used to describe the process of soil water infiltration in Yaoba Oasis. The difference of soil properties had a great influence on infiltration process

and the infiltration rate presented a strong spatial variability.
